I have an assembly that contains a sub-assembly. The sub-assembly is a robotic arm that has two degrees of freedom. I want this robotic arm to be movable at the joints in the higher-level assembly, so I set the sub-assembly to flexible. In the higher level assembly I am able to move one of the joints, but not the second joint. Does anyone know why this is happening?
If I open the sub-assembly in it's own window, then both joints are movable. It just seems to be in the higher level assembly where the second joint remains fixed.
Some more info: the robotic arm subassembly is comprised of several sub-assemblies of its own. All of these second-level sub-assemblies are set to flexible as well.
